When to Use This Skill
- Setting up Faundit webhook handlers
- Debugging Faundit signature verification failures
- Understanding Faundit event types (
item-status,request-status) and payloads - Handling lost-and-found item and request status changes (delivered, finished, expired, etc.)
Verification (core)
Faundit signs each webhook with HMAC-SHA256 (hex) and delivers two headers you care about:
X-Faundit-Signature-Next— current (v1) scheme, signsv1:<timestamp>:<body>(payload integrity). Prefer this.X-Faundit-Timestamp— the timestamp used in the signed string.X-Faundit-Signature— deprecated (v0) scheme, signsv0:<timestamp>only (no body integrity). Avoid.
There is no official Faundit SDK — verify manually. Use the raw request body (before JSON.parse), and build the signed string as v1: + the X-Faundit-Timestamp value + : + raw body.
const crypto = require('crypto');
// Verify the current v1 signature (X-Faundit-Signature-Next)
function verifyFaunditWebhook(rawBody, timestamp, signatureNext, secret) {
if (!signatureNext || !timestamp) return false;
const signedContent = `v1:${timestamp}:${rawBody}`; // rawBody = unparsed request body
const expected = crypto
.createHmac('sha256', secret)
.update(signedContent)
.digest('hex');
try {
return crypto.timingSafeEqual(
Buffer.from(signatureNext, 'hex'),
Buffer.from(expected, 'hex')
);
} catch {
return false; // length mismatch = invalid
}
}

Common Event Types
Faundit sends only two event types. The event-type field names the event; the granular status is the data.status field (not a separate event).
event-type | Triggered when | data.status values |
|---|---|---|
item-status | A found/lost item changes status | contact-missing, waiting-response, wrong-owner, pickup-by-guest, left-behind, finished, shipment-paid, pickup-scheduled, in-route, delivered, deleted, expired, anonymized |
request-status | A lost-item request changes status | registered, not-found, resolved, deleted, expired, anonymized |
Payload shape (both events):
{
"event-type": "item-status",
"data": {
"id": 12345,
"timestamp": "2026-01-15T10:30:00Z",
"status": "delivered",
"locationID": "loc_abc123"
}
}
Note (API v2): Members/
faundit_memberIDwere renamed to Locations/locationID. Legacy IDs are still accepted.
For the full event reference, see Faundit Webhooks docs.

Recommended: webhook-handler-patterns
We recommend installing the webhook-handler-patterns skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):
- Handler sequence — Verify first, parse second, handle idempotently third
- Idempotency — Prevent duplicate processing
- Error handling — Return codes, logging, dead letter queues
- Retry logic — Provider retry schedules, backoff patterns
